HOUSTON, Texas (KTRK) --

For the family of Josue Flores, it must feel like a devastating case of déja vu.

Charges were dropped today against a second suspect accused of killing the 11-year-old boy as he walked home from school last May.

We're taking a look back at this heartbreaking murder and HPD's renewed search for the child's killer:

May 17, 2016Josue Flores had so much life ahead of him. His family said he loved science and math, and was a good student at Marshall Middle School. While walking home from school on a Tuesday, he was stabbed to death by an unknown man.

May 20, 2016Charges were dropped against Calhoun after his alibi checked out, HPD said. That night, Calhoun was released from Harris County Jail to his loved ones. Meanwhile, across town, a candlelight vigil was held to remember the 11-year-old.

"If there's any person sitting in their home or in their apartment and you know something, and you still are not providing that information, shame on you," Turner said.

June 3, 2016HPD announced Andre Jackson was arrested at a Salvation Army shelter, and charged in Josue's murder. Investigators said Jackson had a jacket like the one seen on a suspect who appeared in a surveillance video released to the public.

Andre Jackson was visibly shaking when he went before a Houston judge on Monday.

May 17, 2017The Northside community held a memorial to remember Josue on the one-year anniversary of his death.

July 18, 2017More than a year after being charged in Flores' murder, the Harris County District Attorney's Office said charges would be dropped against Jackson. Prosecutors said DNA evidence was "at best inconclusive" and "in some ways exclude" Jackson as a suspect.
